鋅及鋅合金化學分析方法鉛鎘鐵銅錫鋁砷銻鎂鑭鈰量的測定電感耦合等離子體-發射光譜法The test results of sub - c type showed that middle voltage is higher with 50 u m alloy particle, la - rich alloy has perfect performance at high rate, ce - rich alloy is excellent at high rate and lower temperature, low co alloy is good to decreasing middle voltage except the less recycle life. experiments about the electrolyte showe d that the performance is optimized with contents : koh 78 %, naoh 20 %, lioh 2 % and density 1. 300 g / cm3
對貯氫合金材料粒度和成份進行了粒度分佈測試、成分分析和xrd掃描，並將材料制備成sc型電池進行大電流測試，結果顯示，合金粒度在50 m時，電池放電平臺高，富鑭合金的大電流性能好，富鈰合金有利於電池低溫高倍率放電性能，合金中鈷含量減少雖對電池的放電平臺有利，但循環壽命短。The widely used mg alloy zm5 is chose as the original alloy. on the surface of the molten alloy, a layer of protective film with dense structure is formed by the addition of la, ce or mischmetal. the film prevents the penetration of oxygen and volatilization of mg vapor, and then prevents the zm5 alloy from oxidation and burning
針對目前廣泛應用的zm5鎂合金，通過添加稀土鑭、鈰和混合稀土，在鎂合金液面上形成一層結構緻密並且具有耐久性的保護膜，阻止氧氣的進一步侵入和鎂蒸氣的向外揮發，不再產生鎂的劇烈氧化燃燒現象。The methods for chemical analysis of zinc and zinc alloys - the determination of lanthanum and cerium contents - the tri - bromide arsenazo spectrophotometric method
